The Ubiquiti Ethernet Surge Protector is a network isolator that protects your expensive routers, switches and other equipment from energy surges, lightening and extra energy typical in outdoor antenna applications.

The Ethernet Surge Protector is designed to either drain extra energy to an earth ground or destroy the surge protector instead of seriously damaging your other networking equipment.

We highly recommend using Ethernet Surge Protectors where ever antennas are mounted outside.
